We also examine the route structure configuration that maximizes welfare and whether it can arise as an equilibrium when a regulator implements optimal airport pricing, but does not regulate directly the route structure choice.
One possibility is that transcriptional E2F1 targets could regulate, directly or indirectly, genes involved in the regulation of functions of the endosomal compartment, as per exemple those for the rag proteins.
In addition to the aforementioned results suggesting trans-regulation, our RNAi results suggest that Abd-B can regulate, directly or indirectly, Men expression in cis.
The N-terminal and bHLH domains of OsB1 and OsB2 take advantage of protein-protein interaction with OsC1 that have an R2R3 Myb domain, and these proteins regulate directly the downstream genes of the flavonoid synthesis pathway (Sakamoto et al. 2001; Koes et al. 2005).
As the ECM components interact physically with the cell to regulate directly cell functioning through receptor-mediated intracellular signaling pathways.
Tbx1 has been shown to regulate, directly or indirectly, several of the major signaling systems, i.e. the fibroblast growth factor (FGF) signaling [7], [10], [30], [31], the Retinoic acid signaling [12], [31], the Delta-Notch1 signaling [32] and the BMP/Smad1 signaling (this work).
